Catalina Island's plants and their unique seeds

Flowering plants reproduce by producing blooms that eventually turn into fruits that contain seeds. This issue well follow some of Catalinas most beautiful plants from the moment that their seeds are brought to the Conservancys Native Plant Nurseries and begin their journey back into the wildlands (or even into your own backyard) as home-grown Catalina Natives.

All seeds contain a tiny embryo. These baby plants are usually surrounded by nutritive tissues that help it grow once it sprouts. From each seed, a small root emerges, ready to tap into the soil and begin to absorb nutrients for the growing plant. The seeds found on Catalina are beautiful, strange, diverse and wonderfully adapted to the various conditions and opportunities for plants on the Island. Some are dispersed by wind, others by water, and yet others by animals; a few are dispersed by their own devices. Some seeds are quite large, like the oaks acorns, and some so tiny they look like dust. But all of them are part of the balance of nature onour incredible Island.
